GEARING FOR W'ASHIIDTG MACHINES.

,` Application filed March 7, 1924. Serial No. 697,618.

This invention relates to improvements in gearing for washing machines.

The main objects of the invention are:

First, to provide an improved gearing for washing machines which is compact in structure and very strong and durable.

Second, to provide an improved gearing for washing machines which is assembled as a unit and may be mounted as a unit in the washing frame.

Third, to provide an improved gearing for washing machines which is substantially nois-eless. l

Further objects, and objects relating to f structural details, will definitely appear' from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. rlhe invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

liig. I is an end elevation of a washing machin-eeinbodying the features of my invention, one of the wall panels of the casing being removed.

Fig. II .is a vertical longitudinal section through the gear box, showing the arrangement of the gearing therein.

In the drawing similar reference cl1ar acters refer to similar parts throughout the several views.

Referring to the drawings, I provide a main frame comprising corner uprights 1 and top and bottom cross pieces 2. The casing panels 3 are mounted upon this frame to enclose or house the wash receptacle 4 and the gearing, the panel covering the gearing being removed to show the arrangement of the gearing.

The shaft 5 which is operatively associated with the rotatable element of the machine, not illustrated, is provided with a pinion 6 with which the driving rack 7 coacts. This rack is driven by the crank arm 8 on the crank shaft 9. The driving connections for this crank shaft are housed within the gearing box 10 having a removable face plate 11. This gear box has a projecting arm 12 which is secured to the frame of the machine and also serves as a support for the motor 13. The other end of the gear box is also secured to the frame.

The driving shaft 14 is disposed horizontally within the gear box and projects therefrom into alignment with the motor shaft 15 to which it is connected by the iiexible joint 17.

On the driving shaft are driving Worms 18 and 19. rIhe driving worm 19 meshes with the worm gear 20 having a vertical stub shaft 21 in driving engagement with the vertical driven shaft 22.

The crank shaft 9 has a gear 23 thereon meshing with a transmission gear 24 on the transmission shaft The worm gear 26 is connected to the gear 24 and meshes with the driving worm 18.

llfith this arrangement of parts, I provide a driving gear which is very compact and economical in structure. rIhe gearing is effectively housed so that it may be Well lubricated without grease escaping which is very objectionable in a washing machine.

The gearing, with the exception of the rack and the gear 6 are all enclosed so that there is no possibility of the operator being injured, and the rack and gear 6 are housed within the casing when the end panel of the casing is in position.

The gear box has a removable plate 30 provided with a bearing for the lower end of the shaft 21. This is of convenience in assembling.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a structure of the cla-ss described., the combination of a horizontally disposed driven shaft, a vertically disposed driven shaft, a driven gear on said horizontally disposed driven shaft, a driving rack coacting with said gear, a gear box provided with a projecting arm, a driving shaft disposed horizontally at the botto-m of said gear box and projecting from said gear box above said arm, a motor mounted on said arm and having a flexible joint connection to said driving shaft, a pair of driving worms on said driving shaft, a horizontally disposed worm gear meshing with one of said driving worms and having a driving connection to said vertically disposed driven shaft, a crank shaft projecting from said gear box and provided with a crank at the outside of the gear box, said crank being' connected to said rack, a gear on said crank shaft, and a pair of connected.

transmission gears, one of which meshes with the second driving worin and the other with said crank shaft gear.

2. ln a structure of the class described, the combination of a gear box provided with a projecting arm, a driving shaft disposed horizontally at the bottom of said gear box and projecting from said gear box above said arm, a motor mounted on said arm and having a flexible joint connection to said driving shaft, a pair of driving worms on said driving shaft, a horizontally7 disposed worin gear meshing with one of said driving worms and having a. driving connection to said vertically disposed driven shaft, a

crank shaft, a gear on said crank shaft, and a pair of connected transmission gears, one of which meshes with the second driving worin and the other with said crank shaft gear.

3. In a structure of the class described, the combination of a driven shaft, a driven gear on said driven shaft, a driving rack coacting with said gear, a gear box, a driving shaft disposed horizontally at the bottoni of said gear box and projecting from said gear box above said arm, a motor mounted on said arm and having a fiexible `joint connection to said driving shaft, a driving Worin on said driving shaft, a crank shaft projecting from said gear box and provided with a crank at the outside of the gear box, said crank being connected to said rack, a gear on said crank shaft, and a pair of connected transmission gears, one of which meshes with said driving Worin and the other with said crank shaft gear.

4. ln a structure of the class described, the combination of a horizontally disposed driven shaft, a vertically disposed driven shaft, a driven gear on said horizontally disposed driven shaft, a driving rack coacting with said gear, a gear box, a driving shaft, a pair of driving Worms on said driving shaft, a horizontally disposed Worin gear meshing With the rear driving` Worin on said driving shaft and having a driving connection to said vertically disposed driven shaft, a crank shaft projecting from said gear box and provided With a crank at the outside of the gear box, said crank being connected to said rack, a gear on said crank shaft, and a pair of connected transmission gears, one of which meshes with the second driving worin and the other with said crank shaft gear.

ln witness whereof, l have hereunto set niy hand.
